thanks wardjr, and Iron man.

I think I will order one, maybe two - stuff one on #1 as well, lol

Once you get in on your first, you'll kick yourself for not buying more. Hobb Goblin is awesome!


LOL, i ordered 2 - just because. wink

ordered a couple of spare 8825s, too, also just because - have a back-up Rumba sitting here, as well as a couple spare Ramps boards. I will be ready for just about anything.

For the cost, it is a worth a try...

I print mostly in ABS, but the whole reason for upgrading this printer is to be able to run the nylon on it as well... the moire is an issue that I need to correct.

I ended up changing the driver (sanguinololu) and that pretty much fixed it.  Time for you to chuck the printrboard?

So, to get rid of the moire, what kinds of options do I have, and what would be the "best" one, short of changing out the controller board? (which is an option, but don't really want to go there yet, if I don't have to)

I have seen discussion about the hobgoblin drive gear - but would that be enough by itself? or would i also need to change to a .9 stepper motor? (if so, I will swap controllers before buying another motor)

other suggestions?

I tinkered with the voltage trimpot until it quit - the upper/left is about as good as it gets in the current configuration - not good enough for me.. =P
